I only looked at that one page which is now 2 years old - so you might want to check out later pages to see if Logitech ever fixed those issues.

Second - try a search for "Mac webcams". On the first page of returns - at the top of the page click on the "Search Tools" button and change 'Anytime' to 'Past month' or 'Past Year' to find items relevant to a newer Mac running a current version of OS X.

I would also suggest you search at Amazon - reviews there can be quite helpful.

I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.
